well I turn off the advance option you tell me and finally I am able to 
see the image, although sometimes the image is acquire incorrectly, I 
mean, it  is cut and streched in some parts.  I rescan the image several 
times until the image is acquire correclty.  Do you have any idea how 
should I correct that error.

Thanks

Jose
